Fluke Calibration 1621A-S-156 "DewK" Thermo-Hygrometer Standard-Accuracy Value Kit
Brand:Fluke CalibrationModel No:1621A-S-156Ref No:2724035Our Model No:1621AS156
Product OverviewCalibrated RH accuracy: ±2% RH from 20% RH to 70% RHOperating range: 0 °C to 50 °C (32 °F to 122 °F); 0% RH to 100% RHSuperior accuracyNetwork enabledPowerful logging and analysis toolsTwo interchangeable calibrated sensorsMemory: 400,000 typical individual date/time-stamped readingsUpgraded softwareIncludes standard-accuracy value kit
The standard-accuracy sensors in the 1621A-S-156 ("S" model) read temperature to ± 0.25 °C over its calibrated range of 15 °C to 35 °C. Relative humidity readings are to ± 2 %RH from 20% RH to 70% RH.
The standard-accuracy sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability. Fluke Calibration provides exceptional uncertainties, including total test uncertainty ratios better than 3:1 for both temperature and relative humidity.
The sensors can also measure temperature below calibrated ranges to 0 °C, and above calibrated ranges to 50 °C, with a typical accuracy of ± 0.5 °C. And RH readings from 0% RH to 20% RH and from 70% RH to 100% RH are typically accurate within ± 3%.
Ethernet and Wireless Capability
The Fluke Calibration 1621A-S-156 gives you all of the communications options you expect, and then some. With its built-in Ethernet RJ45 jack, multiple DewKs can be monitored from the same screen using LogWare III client-server software. Ethernet also gives you the possibility for remote connectivity over the internet, so you can monitor critical conditions while you are away.
Cables running along the floor can be a safety hazard, and cables hanging from the ceiling and walls are an eyesore. With the 1621A-S-156, your wireless dreams will come true when you connect your computer through an RF modem, from up to 100 ft. away, without the clutter of extra cables.
Finally, if you need a printout, send data to a printer through the RS-232 interface in real time.
Math and Statistical Functions
In addition to temperature and humidity, the 1621A-S-156 calculates dew point, heat index, and rates of change for both temperature and humidity, without the need to buy additional software. Min, Max, and a variety of other statistics are also calculated and can be shown onscreen. Daily summary statistics, including Min, Max, and maximum rates of change are stored for the most recent sixty days.
Having inputs for two sensors, each measuring both temperature and relative humidity, a single 1621A-S-156 can monitor two locations at the same time. Both sensors can be run via extension cables to remote locations up to 100 feet away, or one sensor can be directly mounted to the top of the 1621A-S-156 unit.
Each sensor is calibrated for both temperature and humidity. The calibration constants assigned to the sensors reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably between different DewK models, and the recalibration of sensors does not require an accompanying DewK.
Sensors may also be assigned a unique identifier (up to 16 characters) to facilitate record keeping by matching the sensor identifier with the collected data. Each DewK ships with one sensor, with additional sensors available from Fluke Calibration.
The Fluke Calibration 1621A-S-156 has enough on-board memory to store up to 400,000 date-and time-stamped data points.
Alarms and Battery Backup
Alarm settings can be set up quickly in the 1621A-S-156, which can be based on temperature, the rate of change in temperature, RH, the rate of change in RH, and instrument fault conditions. Alarms can be both visual (flashing display) and audible (beeping). Likewise, alarm settings can be set up and events triggered in LogWare III. The 1621A-S-156 is also equipped with a 0 to 12 volt alarm output that can trigger a process control system.
A backup battery shuts down the 1621A-S-156's display but maintains measurements for up to 16 hours in the event of a power failure.
One Very Cool Display
Would you like to to view data from across the room? Or from two temperature and two humidity inputs simultaneously? Want to view data graphically, statistically, or both, at the same time? With the Fluke Calibration 1621A-S-156, you can do all of this--up to sixteen different display setups can be stored and recalled at the touch of a single button. And all 16 can be easily modified, so that you get exactly what you want.
If you want to get the most out of your 1621A-S-156, LogWare III is an investment that is worth every penny. As client-server or stand-alone software, it remotely monitors and logs an unlimited number of concurrent log sessions into a single database. That means data from many DewK units can be managed in real time via Ethernet, RS-232, or wireless connections.
LogWare III allows you to customize your graph trace color, alarms, and statistics as you go. You can start/stop log sessions and modify sample intervals from your computer. LogWare III supports "hot-swapping," which allows you to remove and replace sensors without shutting down the log session. LogWare III also supports security features such as passwords for individual users or groups/teams, a built-in administrator account, pre-defined user groups, and customizable permissions.
Never again be the last to know about a problem. Customizable email settings allow you to send emails to designated recipients, including cell phones and PDA's, when a log session begins, ends, or is aborted; when the 1621A-S-156's battery is low; when a sensor calibration is due; or when a temperature/humidity alarm is exceeded.
If you cannot be reached via email, you can always arrange to be paged, instead. Data stored on the 1621A-S-156 can be imported into the software, which is a handy feature when power outages disable the network.
Historical data can be viewed by sensor (model/serial number) location or log session and displayed in a spreadsheetstyle grid. Logged data can also be exported to HTML, RTF or ASCII text for use in your analytical software, or simply print historical data and graphics.
Customizable graphs in LogWare III with zooming capability are an easy way to analyze your data history. Data points that need to be explained can be highlighted, annotated, and referred to later. LogWare III statistics include Min, Max, spread, average, and standard deviation functions, and printed reports keep track of the number of temperature and humidity measurements that were found to be out of tolerance.
